Address Manager includes a data checking feature to help ensure that configuration data is consistent and correct. The Data Checker validates configuration data as it's entered into the system from the web interface, the migration engine, or using the Address Manager API. Use the Data Checker to review issues and potential problems with your configuration before you deploy it to your managed servers.
You can run the Data Checker on demand, or set it to run at a periodic interval. The results of the data checking operation are visible to all users who have at least the view access right for the specific data objects that have identified issues.
When the Data Checker discovers a problem, a Data Check Issues link appears on the page.
To view the Data Checker issues, click Data Check Issues. For more information, refer to Viewing and overriding Data Checker issues.
